Model performance of the NN, CART, SVM, and KNN with fivefold cross-validation in the accuracy, sensitivity, specificity, and AUC for the test data set

	NN	CART	SVM	KNN
Accuracy (%)	85.4	76.1	78.2	77.1
Specificity (%)	88.6	68.9	74.1	82.7
Sensitivity (%)	80.0	79.3	80.0	67.6
AUC	0.92	0.69	0.85	0.76

AUC, area under the curve; CART, Classification and Regression Tree; KNN, K-nearest Neighbor; NN, neural network; SVM, Support Vector Machine.
